MAGAZINE BOLT-GUN.

SPECIFICATION forming part of Letters Patent No. 604,423, dated May 24, 1898.

Application filed April 26, 1897. Serial No. 633,908. (No model.) Patented in Norway June 6, 1896, No. 4,613, and October To all whom it may concern:

Be it known that I, GUNERIUS SCHOU, a subject of the King of Norway and Sweden, residing at Christiania, Norway, have invented certain new and useful Improvements in Magazine Bolt-Guns, (for which I have obtained patents in Norway, June 6, 1896, No. 4,613, and OctoberlO, 1896, No. 4,8175) and I do declare the following to be a full, clear,

lo and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in firearms; and the objects of my invention are, first, to simplify a rifle or similar gun, so that zo its working parts sha-ll be very few in number; second, to so construct the working parts of a riiie or gun that they may be taken apart for cleaning and repair and put together again without tools, both of which z5 points are obviously of great advantage both vide a gun in which the magazine may be illed with cartridges almost in an instant by simply dropping'tllem in, without the resistance of springs, as is usually the case in guns heretofore used; fifth, to so simplify the mechanism of a gun that any ordinary person may readily understand to use it as well as to take it apart for cleaning, &c. These and other objects I attain by the novel construction and arrangement of parts illustrated in 4o the accompanying drawings, in which- Figure 1 is a left side View of the portion of a gun embodying my improvements. Fig. 2 is a top or plan view of Fig. 1 with the stock or woodwork omitted. Fig. 3 is a right side view of Fig. 2 with the arm 42 cut olf at d d.

Fig. 4 is an enlarged partly-sectional top view, as on the line e e in Fig. 3, with the working parts removed. Fig. 5 is a bottom View, and Fig. 6 a front end view, of the hammer-lifter.

5o Fig. 7 is a sectional top View in theleft side of the gun, about as on the line ff in Fig. 1.

Fig. 8 is an enlarged substantially central longitudinal vertical section of the gun with for clearness sake not shown in section. The

following figures, except Fig. 12, are all enlarged to the same scale as Figs. 4, 5, and 8. Fig. 9 is a transverse section of the complete gun, shown as on the line a a in Fig. 8. Fig. l0 is a transverse section on the line b b in Fig. 8, but with all the working partsv omitted. Fig. l1 is a transverse section on the line c c in Fig. 8 with all workin g parts omitted except the cartridge cut-olf. All of said views, Figs. 9, 10, and 11, are shown as looking from the rear toward the front end of the gun. Fig. 12 is a detail bottom view of the cover or lid of the magazine and the cartridge-carrier and its spring. Fig. 13 is a side view, and Fig. 14 a top view, of the ejector. Fig. 15 is a side view, and Fig. 16 a top view, of the spring by which the cartridge-carrier is pressed against the side of the cartridges. Figs. 17 and 18 are detail views of the cartridge cut-off. Fig. 19 is a rear end view, Fig. 20 is a side view, and Fig. 21 a front end view, of the breech-bolt. Fig. 22 is a side view, and Fig. 23 a front end view, of the firing-pin. Fig. 24 is a longitudinal sectional view of the breech-bolt about as on .the line h h in Fig. 19, looking from right to left, and with the firing-pin inserted and the cartridge-extractor im its place. Fig. 25 is a front end View, and Fig. 26 a side view, of the extractor. Fig. 27 is a sectional view on the line g g in Fig. 26, looking from left to right. Fig. 28 is a bottom View of Fig. 26.

Referring to the various parts in the drawings by reference-numerals, 1 designates the stock or woodwork of the gun.

2 is the barrel, which is screw-threaded'at.

3 into the front end of a metallic body or frame 3 4 5, of which the upper portion formsv the receiver, the lower portion the magazine,

and the rear portion houses the hammer and other working parts. The magazine for the cartridges is the annular chamber 7, extending between one-half and three-fourths of a circle around the receiver, and has its front and rear ends terminated by the annular walls 8 and 9, projecting transversely out from the outer curved wall 10 of receiver 4. (Best loo shown in Figs. 8, 9, and 10.) The curved bottom 11 and left side wall 12 of the magazine are made integral and secured in place by the insertion of the ends 13 of the portion 12 upward into the straight grooves 14 in the left extremities of said end walls 8 and 9 and by the stock 1 below it. The right side of the magazine is provided with an opening15, which may be closed or opened, so as to receive the cartridges sidewise into the magazine by moving up or down the curved lid 16, which slides with its .ends in the curved grooves 17 in said end walls of the magazine.

18 is an out and upwardly projecting edge of the lid by which it is operated. In Fig. 9 is shown in dotted line 18 the position of the lid while the magazine is being filled.

19 is the opening through which the cartridges enter from the magazine into the in terior cylindrical space 20 of the receiver in front of the breech-bolt 21, which will presently be fully described. Upon a downwardly-projecting stud 22 swings pivotally the arm 23, which extends through the slot 24 in the wall 9 into the magazine, Where it is provided with a downWardly-projecting arm 25 and a long limber upwardly-curved springarm 26, with a head 95 secured on its end. This arm is the cartridge-carrier, which tends at all times to move the cartridges upward into the receiver and is therefore also urged sidewise by being swung on its pivot 22 by the L-shaped carrier-spring 27X, inserted with its odset end in the side cover 12, as shown at 28 in Figs. 1 and 7, and presses with its L- shaped end 29 against the side of the carrier.

The magazine-lid 16 is provided in its lower front corner with two notches 30 and 31, (see Figs. 7, 8, and 12,) of which the notch 30 isa clearing to allow the tooth 25 of the carrier to swing from side to side. The other notch 31 engages by its rcarshonldcr the said tooth 25, as shown in Fig. 1 2, and thereby positively locks the carrier,which, being spring-pressed, assists in holding by frictional contact the lid in the open position 18X in Fig. 9, with the head of the carrier standing back, as to the left in the view, into the cavity 32 in the side lid 12, as shown in dotted line in Fig. 9, thus leaving the magazine open and unobstructed, so that all the cartridges it will hold can be dropped sidewise down into it in a moment, and as the lid is touched upward again it closes and the gun is ready foriiring.

The cartridge cut-off (best shown in Fig. 18 and in the front end view, Fig. 17) consists of a small rock-shaft 33, provided near its middle with the thumb-catch or arm 34. The front end of this shaft is cut away, forming a half-round 35, which will alternatelypresent its round orlat side to the cartridges, and thus will either prevent them from or allow them to enter the receiver, according to how the shaft is turned by the catch 34. 'lhe front portion 35 of the shaft is inserted in a hole 36 in the upper wall of the receiver, so that it may present its round side to the cartridge when in the position 36X, as shown in Fig. 9. The rear end of the shaft is journaled in a lip or projection 37, formed upon the rear end of the receiver and provided with the notch or gap 38 for the arm 34 to pass through in extracting and inserting the shaft. In the lower side of the rear half of said rock-shaft is inserted and secured a spring-arm 39, of which the downwardly-curvedfront end 40 engages the transverse groove 41 and, by frictional contact, holds the shaft in the desired position, as well as prevents its accidental withdrawal.

The breech-bolt 2l, provided with the operating-arm 42, is in its lower side provided with a longitudinal groove 43, closed at its front end and having itsrear end broadened into a wide notch 44. The ejector 45 (best shown in Figs. 8, 13, and 14) is a small two-v armed lever pivoted in a short groove 46 in the bottom of the receiver. (See Fig. 8.) Its short end projects upward into the groove 43 of the breech-bolt and allows the long front end to sink down into groove 46; but when the breech-bolt is pulled back to its full limit the solid front terminus 42 of the groove 43 depresses the short end of the lever, causing thereby its front endto knock the empty cartridge upward and out of the receiver, and when the breech-bolt is pushed forward and turned to the right, so as to cause its lockinglugs 47 and 48 to enter the locking notches or cavities 49 and 50 in the upper wall of the receiver and the arm 42 to enter the notch 43 in the side of the receiver, the ejector occupies the Wide portion 44 in the under side of the breech-bolt. Between the cheek-plates 51 of the frame I mount on the two plain pivots 52 53 the hammer 54 and the trigger 55. The mainspring 56 (best lshown in Fig. 8) is connected with the hammer by the stirrup 57 and is further held in place by the cheeks 51 and the notch 58 in the rear end wall of the frame. 59 is the trigger-spring, which is secured with its upper end to the rear tang 6 of the frame and presses with its lower end forward against the trigger.

The breech-bolt 21 houses in its round central opening 61 the firing-pin 62, of which the front end 63 is reduced, as usual, and its main body is round, while its rear end 64 is four-cornered as far as to the rigid collar 65, with which the pin is provided. This collar is housed in a cylindrical cavity 66, formed ICO in the reduced end 67' of the breech-bolt,which projects rearwardly beyond the operating-lever 42. The bottom of said cavity 66 and the front side of the collar 65 are both provided with cams, as 68, which when meeting the tops of one another keep the firing-pin retracted, so it cannot touch the cartridge; but if the breech-bolt is turned so that its cams 68 register with the spaces between the cams on the firing-pin the latter is at liberty to be thrown forward by the blow of the hammer upon its rear end and will then operate on the cartridge. The necessary turning .of the breech-bolt for said purpose takes place every time the breech -bolt is rocked about oneeighth of a turn to the right to interlock it in the receiver and back, so as to allow its retraction. The firing-pin is prevented from rocking or turning by having its square end inserted in the square hole 69 in the rear end portion 70 of the cartridge-extractor 71,which portion is provided with the cylindrical cavity 72, fitting upon the projection 67 of the breechbolt. The tongue 73 of the extractor engages the annular groove or recess 74 at the base of the operating-lever 42. (Best shown in Figs. 2l and 24.) The front end of the extractorbar 71 is brought down to the side of the front end of the breech -bolt, which it projects slightly beyond and is formed into the hook 75, adapted to take hold in an annular groove near the rear end of the cartridge and extract it from the barrel after it is fired. Upon the right side of the extractor-bar, near its front end, is provided the stop 76, which when the breech-bolt is pulled back catches against the rear terminus of the notch 50 in the upper part of the receiver. This notch is shown in Fig. 8, and in Fig. 2 it is indicated in dotted line that its front end is open in order to receive said catch or projection 76. 77 is a clearing in the front end of the receiver for the hook of the extractor to pass into and reach the regularmotch (not shown) in the end of the barrel and get a hold of the cartrdge.

The hammer is raised by the pressure against its front side orprojection 54 of the square rear end 78 of the hammer-lifter 79, (shown in Figs. 5, 6, and 8,) which is of almost semicylindrical shape with a diagonal front cam edge 80, of which the rearmost end terminates in the notch 81 and the front end in the squared-o point 82. 83 is a catch projecting from the under side of the hammerlifter and serves to prevent the latter from dropping out accidentally when the breechbolt is removed. This hammer-lifter is lo' cated in the recess 84, (best shown in the plan view, Fig. 4,) milled out for it in the receiver, so that its upper or inner curved face fits the lower face of the breech-bolt. When the hammer-lifter is inserted into said recess, the catch 83 on its bottom is slipped down into the deeper recess 85. Said recesses run diagonally and parallel with the front edge 8O of the hammer-lifter, which bears against the front terminus 86 of the recess 84. When the parts are put together and the breechbolt is pushed forward, the hammer-lifter fills the space between the shoulders 89 and 90 in Figs. 19 and 20, so that it is bound to rock with the breech-bolt and thus be moved forward by the diagonal recess and leave the hammer free to work when the breech-bolt is turned to the right and interlockcd and at no other time, and by raising the arm 42, preparatory to pulling the breech-bolt back, the hammer-lifter is, by the coaction of the diagonal cam edges 8O and 86, forced rearwardly against the hammer, which is thereby raised to its full limit. When the breechbolt is pulled back, the hammer-lifter is prevented.from turning by. having its notch 81 held by the hammer forward against the projection 91, adjacent thereto-in the recess 84 in the receiver. When the breech-bolt is again moved forward and turned to the right, the hammer-lifter turns with it and releases the hammer, which after losing the support of the lifter depends on the trigger to hold it up, and is thus ready to strike when the trigger is pulled.

92 is the opening in the receiver through which the empty cartridges are ejected, and 93 is the slot in rear thereof in which the extractor-bar 71 guidingly slides back and forth.

In the above description the operation of the gun is already fairly explained. It may,` however, be further stated that when the magazine is filled with cartridges and the eartridge cut-0E is turned so as to allow thecartridges to enter the receiver the operator simply takes hold of the arm 42, raises it up, and pulls it back so that the cartridge can slip partly sidewise into the receiver. He then pushes the breech-bolt forward and locks it by turning it to the right, then pulls the trigger, andafter thus firing one shot he repeats the operation with the breech-bolt and lthe trigger just as fast as he wishes and' is able to, and everything works automatically until the magazine is empty, when he refills it in the way above described. In pulling the breech-bolt back quickly the empty cartridge, which follows the hook 75 of the extractor, is thrown out of the receiver by the ejector 45, as already described, and when the breechbolt is moved forward its right front edge adjacent to the mouth 19 of the magazine .takes hold of the edge of the rear end of 'the cartridge and moves it forward, while the next cartridge or the cartridge-carrier itself urges it inward until it is freed from the retaininglip 96 and assumes a central position with and is pushed toward the center of the receiver. The inclined plane or shoulder 97 at the rear end of the receiver serves to guide the arm 42 quickly into its locked position, and in raising the arm 42 said shoulder gives the breech-bolt and extractor a very powerful start rearwardly, thereby starting the empty cartridge, which sometimes from the force of the shot is slightly swelled out and has a tendency to stick in the barrel.

IOO

IIO

The parts of the gun which ordinarily need Y cleaning may be taken apart and put together without tools of any kind whatsoever in the following manner: I ull the breech-bolt back, with the front end of the extractor sprung upward, s o that its' projection 76 passes above the receiver. After thus removing the breechbolt and extractor the latter may be separated from the former by moving its tooth 73 along and out of the groove 74, then moving it rearwardly out, off the projection 67 of the breechbolt. This will give access to the breech and the receiver. The cartridge eut-o may be removed by raising its thumb-piece 34 npward and pulling it out against the frictional resistance of the spring-hook 39 40. The part l1 l2 is simply to be pulled downward, and the lid 16 may then be pushed out to the left. The cartridge-carrier may next be swung out of the notch 24 and dropped down from its stud22. The carrier-spring, being fastened as shown, may also be dropped from its place when not held by the carrier. The pivots in the trigger and hammer may be pushed out, as they are not screw-threaded. The triggerspring may he permanently fixed in the rear end of the receiver and the main or hammer spring, being held in the manner shown, may be removed and reinserted Without tools. There is not a single screw in the entire mechanism. rlhe only three screws (98, 99, and 100) in the entire gun are for securing the stock or Woodwork to the iron. To assemble or put the parts together, the proceeding is exactly the reverse of that just described for taking it apart.

From the above description it will be seen that I provide a gun which maybe red very rapidly, and it may have its magazine refilled in a moment and its parts made strong, durable, few, and easy to take apart for cleaning, all of which points are very important, especially in guns used by the army, where sand and dust will often be apt to get into the mechanism, requiring frequent removal and cleaning of the Working parts most exposed to such incidents, and that for such cleaning of ordinary guns a box of tools is required, and the many small parts and still smaller screws are very apt to get lost, all of which diliiculties I overcome in my invention.

The front locking-notch 49 for the bolt-lug 47 may extend to the top of the receiver, as in Fig. 10, and the stock need not necessarily extend underneath the magazine, but may have a clearing there to admit of the removal of the bottom of the magazine, if so desired; but usually the magazine will need no cleaning, so I mention it more in order to show that even the magazine may be taken apart without tools or removal of the stock, as a spring-catch may hold its bottom and permit it to be removed by applying suitable force or by pressing on a locking-spring.

lIaving thus described my invention, what I claim, and desire to secure by Letters latent, is-

l. In a magazine bolt-gun, the combination with a receiver and a breech-bolt moving back. and forth therein; of a magazine communieating therewith and forming a part of a cylinder around the receiver and having a lid or cover for admitting the cartridges to be dropped. sidcwise down into the magazine without changing the position of the gun and a spring-actuated cartridge-carrier adapted to feed the cartridges into the receiver, said cover consisting of a curved plate sliding with lts ends in sultably-provided curved grooves and which presses the carrier back and locks it so it offers no resistance to the filling of the magazine, and when the cover is closed the carrier is set free to chase all the cartridges toward the inlet to the receiver, said cover having also a projection by which it is easily operated, substantially as and for the purposes set forth.
